THz generation by optical rectification and competition with other nonlinear processes
Résumé
We present a study of the competition between THz generation by optical rectification in ZnTe crystals with two-photon absorption and second harmonic generation. The incident pump field for optical rectification is shown to be depleted by two-photon absorption and the generated THz field is shown to be significantly absorbed upon tight focusing by free-carrier absorption.
